I use 64 bits computer and i have no problems. 64 bits is more trustable. If you want to use it on 32 bits, check it by yourself and tell your results here. You would help someone like you by your answer.
What does any of that even mean. 32-bit Windows is still Windows and the majority of installer programs and most other software you use is 32-bit or has 32-bit separate installers. One is not inherently more "trustable" than the other. In fact, 64-bit windows contains the entire 32-bit subsystem inside of it. I mean look at your Program Files (x86) folder and tell me it is not populated.
